Answer:
x = [tex]21^{o}[/tex]
Step-by-step explanation:
The opposite sides of the parallelograms are equal and parallel to each other. Thus, from the alternate angle principle (alternate angles are said to be equal), then;
2x = 42 (alternate angle principle)
x = [tex]\frac{42}{2}[/tex]
= [tex]21^{o}[/tex]
x = [tex]21^{o}[/tex]
Therefore the value of x in the question is [tex]21^{o}[/tex].
